Hi community,

There is no unified way of syncing RGB lighting between brands. Brands all have their little ecosystem: it can be confusing and sometimes even overwhelming.
I took the initiative to start quick guides on how to setup a system per brand. In my next comments there will be very poor attempts of mine to create Schematics for different RGB solutions.

So everyone on the forum, can quickly look up how the RGB-solution of their favorite Brand works! CORSAIR
Corsair LL/SP/HD RGB fans have two cables/headers: One is a 4-pin connector for power, the other a RGB header.

Plug the RGB header in the Fan hub and plug the 4-pin power connector in the commander pro (up to 6x fans).
Then connect the fan hub via the LED header to the commander pro. You can also connect your Corsair LED-strips - trough the LED header - to your commander pro
Both commander pro and fan hub are SATA-powered.

Connect the commander Pro via a USB 2.0 header to the motherboard.

You can now control  your fan speed and lighting with the provided Corsair software.  
Product list:
- Corsair LL120 Fans 3x Pack + included Fan Hub (100$)
- Corsair Commander Pro (70$)
- Corsair LED strips extention kit (30$)     NZXT NZXT Aer fans have two cables/headers: One is a 4-pin connector for power which goes in the motherboard, the other an RGB header which goes in the HUE+.

The NZXT fans can be daisy chained with fan-to-fan-connectors using the IN and OUT headers.  Then the last fan connects to the HUE+ with a fan-to-LED-connector into one of the 2 channels that can host up to 5 fans.
In this illustration, the 2nd channel connects to the NZXT LED Strips.
The HUE+ is molex-powered and connects via USB 2.0 to the motherboard. If you don't want to or cannot plug your fans to the motherboard, there is an option to plug the fans into the GRID V3: it's a fan controller sold by NZXT (up to 6x fans).   Finally, you can control your fan speed & lighting and led-strips with the provided NZXT Software.
    You'll notice both USB2.0 Headers on the Mobo are taken, that's why NZXT sells an internal USB-HUB to provide further USB2.0 headers.   Product list: - NZXT Aer 120mm RGB 3x Pack (70$)
- NZXT Hue+ (60$)
- NZXT Grid V3 (45$)
- NZXT LED strips extension kit (25$)

- NZXT USB Hub (25$)   COOLERMASTER Coolermaster RGB fans have 2 headers: One 4pin power connector that goes into the motherboard and one that goes into the Coolermaster RGB controller

Each coolermaster fan connects via an RGB cable into the Coolermaser RGB controller. You can connect up to 4x fans in the controller, however you can increase this number by using a Splitter like shown below. Splitters like in the illustration are to be bought seperately, however Coolermaster provides 4x RGB cables with the controller.
You can plug the Coolermaster RGB strip into the Coolermaster RGB controller with a provided RGB cable.
The RGB controller is SATA-powered.

Unfortunately, Coolermaster does not provide any sort of Fan Hub for fan control, you will have to use your Motherboard Sys_Fan headers or 3rd Party fan hubs like the thermaltake Commander FP for PWM (15$) which can accommodate up to 10x Fans. Another option would be using the NZXT Grid+ V3 so you can monitor the fans rpms trough the Cam Software.

The Coolermaster RGB controller connects to the motherboad via USB 2.0.
Finally, you can control your lighting with the downloadable Coolermaster Software.   Product list: - 3x Masterfan Airbalance RGB + included RGB controller (60$)
- Coolermaster RGB strip (25$)
- Coolermaster RGB cable splitter (15$)   - Thermaltake Commander FP for PWM (Fan Hub) (15$)
- NZXT Grid+ V3 (Fan Hub) ($49) THERMALTAKE Thermaltake RGB fans have 1 Header that goes into the TT Sync for RGB control.

Each Thermaltake fan connects via an RGB header into the TT Sync. You can connect up to 9x fans in the controller.
You can plug the thermaltake lumi rgb strips into the TT Sync with a provided RGB cable, you then do not need the included little RGB controller anymore.

The TT sync is SATA powered and hosts up to 9x fans
The TT Sync connects to the motherboard via USB2.0 header.

Finally, you can control your fan speed & lighting with the Thermaltake Software     Product list: - Thermaltake RGB Riing PLUS 120 3x Pack (80$)
- TT Sync (30$)
- Thermaltake Lumi Plus LED strip (45$)   ENERMAX The Enermax TB RGB Fans have 1 cable/header: they each go in the included Fan & RGB controller (up to 8x fans). This is by far the most practical solution cable management-wise and the cheapest.

The controller connects to the motherboard via RGB header. WARNING, this will only work with motherboards with RGB Headers. In my experience, only the most recent Motherboards are equipped with those.
If you don't have RGB Header on your motherboard, you can use the Infrared Scanner Cable in order to remote-control your fans with the included remote-control.
You can connect up to 2x RGB strips to the controller via RGB Header. Adapters are included for universal compatibility. The LED-Strips in the illustration is a Phanteks RGB Strip.
The controller is Molex-powered.

Finally, you can control your Fan lighting with your motherboard software and their speed with the remote control. If you don't have your Fan Controller connected to the motherboard, you can control the lighting with the remote control.   Product list: - ENERMAX TB RGB Fan 120mm 3 in 1 + included Fan Controller & Remote control (60$) - Phanteks LED strip (15$)

DEEPCOOL MF120 The Deepcool mf120 fans have 1 micro-usb cable/header that goes directly into the hub   The Hub has 4-Pin PWM header going into a Sys_Fan so you can control the RPMs with your motherboard.
The Hub connects to your modem per WiFi and requires you to download the Deepcool Fan & RGB control phone APP on iOS or Android.
You can also set the fans RPM on the Deepcool phone APP.
The Hub is SATA-powered

    Product list: - DEEPCOOL MF120 3in1, Smart Fans (110$)   DEEPCOOL RF120
  The Deepcool RF120 fans have 2 Headers: 1x 4-pin PWM that goes into the included Fan Hub & 1x RGB header that goes in the RGB splitter.

The included Fan Hub can host up to 4 fans and the splitter up to 3 or 5 fans (technically 5 if you plug a 2nd included splitter into the "main" splitter).
There are 2 kind of splitters: One with a mini-controller and one without. If you have an Asus motherboard with an RGB header, then you should use the splitter without the mini-controller that connects to the fans on one side and connects to the motherboard on the other side.
However, if you do not posess an Asus motherboard or if your Asus motherboard does not have an RGB header, then you need to use the RGB splitter with the mini-controller that connects to the fans on one side and connects to the PSU via SATA on the other side.

Finally, you can control the Fan speed via your motherboard software or BIOS trough a single Sys_Fan header since you're using the Fan Hub.
And you can control the RGB lighting with either Asus Aura or the mini-controller.
